- SPRAY-Nozz'Ln.

To all ivhom 'it mai concern? Be 1t known t at I, LUCIAN W. CUSH- MAN, a citizen of the United States, residing at Lincoln, in the'county of Lancaster and State of Nebraska, have invented a new and useful Spray-Nozzle, of which the followinis a specification.

his invention relates to spray nozzles and has for its principal object to provide a nozzle of simple and economic construction through which vliquid may be forced and distri uted in a finely diffused spray. A further object of the invention is to provide anozzle havingv a minimum numer of parts and to so construct the nozzle that it may be readily adj-usted from a spray to a direct jet nozzle.

With these and other objects in view as will more fully hereinafter appear, the invention consists in certain novel features 'of `-'construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that Various changes in the form, proportions, size and minor details of the 'structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

-In the accompanying drawings z-Figure 1 1s aside elevatlon of a nozzle constructed in accordance with the invention. Fig. 2 is a section 'view of the same. Fig. 3 is an end view of the body of the nozzle. Fig. 4 is a similar View looking from the opposite end, the liquid supply pipe being shown in section.

Similar numerals of reference are employed. to indicate corresponding parts throughout the several figures of the drawin s.

n carrying cit -the invention a single piece nozzle body 5 is employed comprising threaded and screwed thereon is the annucommunicate.

between the same a chamber 18 with which the channel 9 and thedischarge orifice 16 Further'v said washer bears against the marginal4 portion ofthe disk and produces an effective liquid tight joint.

Experience has demonstrated that this nozzle is Very effective and that it will produce a finely diffused spray. There are no 'internal removable parts through the body which-are likely to become corroded in place or lost when the nozzle'is 'taken apart;, The channel from the conduit is comparatively large so that there is no danger of clogging.

Moreover because of the conformation there.- of the liquid is forced outward-ly through said channel' and is driven against the capA or disk at an an le which causes the liquid to, flow rapidly inthe' little chamber, said liquid b'eingftinally discharged through the orifice in, the disk where the .same has aV whirling motion thus causing a very fine spray under ordina-ry pressure.

Extending through the central portion of the face plate; 6 is ali-opening that is in di rec-t 4alinement with the opening 16. The opening in the plate is threaded and normally is plugged by a screw 20. This screw may be removed at pleasure in order to secure a vdirect. passage from the chamber 9 to the outlet 16 so that a portion of the liquid may be directed from the nozzle in the form of a jet. v

that is claimed is 1. In aspra-ying nozzle, a body portion having a tortuous channel andan axial passage, means removably inserted 1n the axial passage, and a cap upon the body having a central discharge opening.

2. In a spraying nozzle, a body portion having a tortuous channel and a threaded axial passage, a threaded plug removably screwed into the said passage, and a cap passage.

3. In a spraying nozzle, a body portion having a tortuous channel and an axial pas- J sage, aboss projecting from 'the body and threaded to receive a conduit, a plug inserted `in lthe said passage and removable through'vthe conduit receiving opening in the boss', and a cap upon the body formed with an axial discharge opening. h

4. In a nozzle, a body portion having a helical. channel and a direct axial passage,

' a' `removable plug normally closing said pased connection With the body sage, a disk arranged in front of the body portion and provi ed With a central opening, a packing Washer ,between the disk and the body portion, and a cap having a threadand serving to hold said disk in place. In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two Witnesses.
